Abstract:

INTRODUÇÃO: A endometriose, uma doença benigna, tem características invasivas com potencial proliferativo. O desenvolvimento das lesões pode ocorrer em decorrência de crescimento celular glandular e/ou estromal ou de alterações na cinética celular. Cinética celular refere-se ao equilíbrio entre a morte celular, ou apoptose, e a proliferação celular, que pode ser avaliada pela expressão de fatores de crescimento como, por exemplo, a topoisomerase 2-alfa (TOP2A). Também influenciam a cinética celular oncoproteínas como p53 e c-erB2, conhecidas por interferir na apoptose, podendo resultar em onco

INTRODUÇÃO: Apesar de a endometriose profunda (EPF) ser a forma da doença de maior repercussão clínica, os estudos sobre a doença costumam ser baseados em lesões de endometriose ovariana (EOV) e peritoneal (EPT). A patogênese da EPF ainda é objeto de amplo debate, pois há poucos estudos feitos exclusivamente com lesões de EPF. O fator de transcrição codificado pelo gene homeobox A10 (HOXA10) regula a conferência de identidade tecidual de útero ao ducto paramesonéfrico indiferenciado durante o período embrionário. O gene mantém um padrão de expressão temporal e espacial bem definido e, durante

Abstract:

Early this century "S-shaped" curves, sigmoids, gained popularity among demographers. However, by 1940, the approach had "fallen out of favour", being criticised for giving poor results and having no theoretical validity. It was also considered that models of total population were of little practical interest, the main forecasting procedure currently adopted being the bottom-up "cohort-component" method. In the light of poor forecasting performance from component methods, a re-assessment is given in this thesis of the use of simple trend models. A suitable means of fitting these models to cens

Abstract:

This thesis presents the use of a new sigmoid activation function in backpropagation artificial neural networks (ANNs). ANNs using conventional activation functions may generalize poorly when trained on a set which includes quirky, mislabeled, unbalanced, or otherwise complicated data. This new activation function is an attempt to improve generalization and reduce overtraining on mislabeled or irrelevant data by restricting training when inputs to the hidden neurons are sufficiently small. This activation function includes a flattened, low-training region which grows or shrinks during back-pro

In this work we apply the Adomian decomposition method to an orientation aggregation problem modelling the time distribution of filaments. We find analytical solutions under certain specific criteria and programmatically implement the Adomian method to two variants of the orientation aggregation model. We extend the utility of the Adomian decomposition method beyond its original capability to enable it to converge to more than one solution of a nonlinear problem and further to be used as a corrector in path following bifurcation problems.

Abstract:

El documento digital no refiere asesor<br>El vólvulo de sigmoides es una emergencia frecuente en los hospitales del área andina, donde representa más del 50% de todas las obstrucciones intestinales. El Dolicomegacolon Andino (DCMA) y la mesocolonitis retráctil son los principales factores predisponentes del vólvulo; la mesocolonitis aproxima el segmento proximal y distal del asa sigmoidea, favoreciendo su torsión. La ingesta copiosa de alimentos fermentables constituye el factor precipitante del vólvulo; la mayoría de los pacientes son atendidos durante las épocas de cosecha y siembra, período

Abstract:

BACKGROUND: The recent development of the ocular vestibular evoked myogenic potential (oVEMP) test protocol in addition to the cervical vestibular myogenic potential (cVEMP), can provide clinicians information about the functioning of the otolith end organs and their enervating pathways. The utilization of cVEMPs and oVEMPs together may also provide feedback on the success of the surgical attempt to preserve the cochlear fibres during vestibular neurectomy (VN), highlighting the need for including both oVEMPs and cVEMPs in Menière s Disease (MD) subjects post VN.

Abstract:

The suboccipital craniotomy is one of the most commonly performed neurosurgical approaches to the posterior fossa. Surface landmarks help the surgeon to identify and avoid damage to vascular and neural structures related to this approach, as the sigmoid sinus and facial nerve. We have defined a new cranial landmark, the digastric point, and we studied the relationships of this point with others surface landmarks, like the asterion, jugular point, stylomastoid foramen, jugular foramen and sigmoid sinus sulcus. Craniometric measurements were made in 127 dry human adult skulls, 90 male and 37 fem
